LANSINGB. SWAN, 0F ROCHESTER, NEW YORK.

ATMOSPHERIC SODA-WATER FOUNTAIN.

Specification of Letters Patent No. 995, dated November 3, `1838.

To all whom it may concern:

Be it known that I, LANSING B. SWAN, of the city of Rochester, in the county of Monroe and State of New York, have invented a new and Improved Apparatus for and Mode of Preparing Soda-Water; and I do hereby declarethat the following is a full and eXact description.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation. I construct a cylindrical receiver or air vessel A of tin or copper o-r other suitable material, with convex ends B of suicient capacity to contain about four gallons more or less, be-

ing about 20 inches in length and about 9 inches in diameter more or less. I place this vessel in a wooden tub C of suiiicient dimensions to contain ice for cooling. Through the center of one of the heads of this cylinder I insert a tube of tin or some other suitable material D about of an inch in diameter descending to the bottom and open at the ends E E. In .this tube I insert a stop cock F, and at its upper termin nation attach a discharging pipe G with an orifice 35 of an inch in diameter. Through the margin in the same head of the cylinder I also insert another tube of similar material and dimensions H, o-pen also at the ends and in like manner descending to the bottom. At the upper end of this tube I sometimes for the better security of the liquidin the cylinder or air vessel place a valve opening downward I, connected by means of a lead pipe K of about the same diameter, with the discharging aperture L of a forcing pump M, about 12 inches in length and 2 inches caliber. This pump I construct of Zinc or some other suitable material with a packing box at the top N around the piston rod, a valve in the piston opening inward O, and also a valve P at the bottom of the pump opening in the same direction. To the lower end or receiving aperture of the pump R, I attach a lead pipe of the same diameter as above T and of suiicient length `to pass into a reservoir of stone or some other suitable material W of suiicient capacity to contain about 12 gallons more or less, and placed in a cellar or at a convenient distance in any other situation.

To put my fountain in operation, I prepare any 0f the varieties of syrup in the usual form, and dissolve in each gallon of the samev 7 ounces of tartaric acid.v I then i put into the reservoir any quantity ofpure water which it will contain and "dissolve in each Gallon thereof 1 ounce of supercarbonate o? soda. I then apply thehand to the pump and after forcing into the air vessel or cylinder a suiicient quantity of the solution desired. I pour into a pint tumbler about 1 fluid ounce of the syrup preparedasbefore mentioned and open the stop-cockfuntil the tumbler is filled.`

The manner of its operation in producing of supercarbonate of soda from the reserf,`

voir, to procure as rapid" a dlscharge as 1s-V pressed and being a very elastic fluid its eX- pansive power is exerted upon the liquids in the cylinder, causing it to pass out `rapidly when the stop-cock is opened. The syrup containing an acid and the Vliquid in the cylinder or fountain a. carbonated alkali, the

instant they are brought in contact a chemical decomposition takes place, carbonio acid gas is produced, and the consequent effervescence ensues.

Having thus fully Adescribedthe construction and operation of my atmospheric soda water fountain, I do hereby declare that I do not claim as my invention either of the individual parts of the apparatus described, the various devices used by me being such as are well known and in common use, but asI verily believe not combined together and coabove set forth.

What I do claim, therefore, is The placing of a carbonated alkaline solution in a suitable vessel for Vcontaining the same, and causing it to pass, as wanted, into LANSING B. SWAN.A
